How to Deal with Rainwater Entering the Car Window?

Then clean up the residual water on the floor of the car. If the vehicle's computer has been soaked in water, it also needs to be replaced. In addition, there is a drainage pipe in the position of the co-pilot. It may be caused by a leak at the pipe interface, a blocked sunroof drain, or blockage by dust and impurities.

Last time my car window leaked during the rain, it really annoyed me. I spent half a day trying to soak up the water with an old towel, but it didn't help. Later, a friend told me that the window seal might have aged - rubber tends to harden and crack after prolonged sun exposure. Now, every time I wash my car, I make sure to check the seals for cracks, and I've bought a bottle of rubber conditioner to spray regularly. Dust accumulation in the window track is another big issue - using a small brush to clean out the sand and dirt from the track gaps is crucial. Most importantly, the drainage holes at the bottom of the door: I once found three out of four holes blocked, and when I unclogged them with a paperclip, about half a bottle of water poured out. Before rainy season comes, I always keep some silicone strips on hand for emergencies - if I notice any leaks, I can temporarily patch them up. These small things are easy to overlook, but when you're driving in the rain with blurred vision, that's when you really regret not paying attention.

I've learned my lesson with window leaks the hard way—once after a heavy rainstorm, my trunk was filled with water like a fish tank. The mechanic told me that water leakage through car windows usually stems from three issues: deformed sealing strips, clogged drainage holes, or damaged waterproof membranes inside the doors. When dealing with it myself, I first soak up the water with a cloth, then use the cool setting on a hairdryer to slowly dry the interior of the door. The drainage holes at the bottom of the door panel must be cleaned regularly—just unclog them with a toothpick. If you hear sloshing water inside the door, it means the waterproof membrane needs replacing. Also, when parking, avoid prolonged exposure to direct sunlight, as rubber components can't withstand such abuse. Before the rainy season arrives, it's helpful to get a waterproofing test at an auto repair shop—they use high-pressure water jets to simulate heavy rain and test the seals.

Last year during the rainy season, my car windows leaked badly. After some research, I found the reason was quite simple. The window glass didn't fit tightly with the door frame, and the rubber seal would shift during operation, allowing water to seep in. When I handled it myself, I first wiped dry the accumulated water, then used chopsticks wrapped with cloth strips to absorb water from the door gaps. The most crucial step was to check the small holes at the bottom of the door - those are drainage channels. After unclogging them, the accumulated water drained out immediately. If you often park under trees, clogged drainage holes from leaves are the most common issue. Now I clean the drainage holes monthly and always keep dry towels in the trunk for emergencies. The sound insulation foam in doors absorbs water and is particularly difficult to dry - you need to remove the door panel to air it out.
